Patent DE-19642088-A1 (DE)
Title: Manufacturing a micro:textured component
Inventor: KRAGL HANS DR
IPC: B29C39/10
Filed: 1996-10-12
Abstract: In a process for manufacturing a microtextured component a casting mould comprising a casting frame (20) and a second base plate, forming a mould punch (10), is filled with a liquid reactive material (27) which is then cured and parts of the mould, especially the casting frame, form part of the microtextured component. Both the second base plate and casting frame (20) are produced by microtexturing methods giving very accurate components. A process for manufacturing a casting frame (20) involves placing a profiling frame with an opening on a first base plate, then locating an insert in a recess on the base plate to form a surrounding gap relative to the profiling frame. A castable material is poured into the gap and cured to form the frame (20). In a process for manufacturing the first and second base plates a protective coating is applied to a profiled, e.g. etched, substrate to create a positive raised structure which is then etched to form a positive a master suitable for forming the negative impressions used as base plates. The protective layer for forming the vertical wall of masters for both base plates is created by the same mask and the contour of the vertical wall around the raised structure of a master is the same for both base plates. A microtextured component comprising a casting frame (20) filled with a cured reactive casting material (27) is claimed. Also claimed is an integrated optical component employing the microtextured component. A recess in the cured casting material contains a filler material and acts as a wave guide. A claimed casting frame (20) has a carrier member (80) for holding one or more electrical, optical or electro-optical components (26) and an opening (21) for filling with curable casting material (27).  Preferably the second base plate is made from a ferromagnetic material and is held in position on a carrier plate (12) by magnetism. The casting frame (20) has one or more inverse roof-shaped carrier structures which engage with corresponding projections on the second base plate and a carrier (80) of the casting frame supports an electrical, optical or electro-optical component while the casting frame is placed on the second base plate. Material (27) cast into the frame (20) is cured by heating, preferably over a large area at the base and raised projections in the recess of the second base plate form a negative impression in the cast material of the integrated optical component. A current supplied to an electrical or electro-optical component can be used to assist curing of the cast material (27). Location of the profiling frame on the first base plate is effected by one or more elements in the latter.

Title: Method for determining light transmission time over measurement path
Inventor: BLOEHBAUM FRANK
IPC: G01S17/14
Filed: 1996-10-28
Abstract: The method involves a transmitter (1) transmitting a modulated signal s(t) along the measurement path. The signal is converted in a receiver (4) into a reception signal e(t) and evaluated in the measurement appliance. Between the two signals, a correlation function k(t) is formed by transforming the signals in the frequency domain.  In the frequency domain the spectrum K(f) of the correlation function is calculated from the spectra S(f) and E(f) of the transmission and reception signals. Finally the correlation function is determined by inverse transformation in the time domain. The maximum kmax = k(tmax) of the correlation function is derived and tmax is evaluated to obtain the signal transmission time
